Description

Lorsque l'on effectue la rectification des rails d'une voie de chermin de fer, c'est-à-dire l'élimination des déformations, notamment ondulatoires, de ces rails par enlèvement de matière et reprofilage du champignon du rail à l'aide de meules rotatives on crée une grande quantité de poussières comprenant les particules meulées du rail ainsi que les particules abrasives et de liant arrachées à la meule.When carrying out the rectification of the rails of a rail of chermin of iron, that is to say the elimination of the deformations, in particular undulatory, of these rails by removal of material and reprofiling of the head of the rail at the With the help of rotating grinding wheels, a large amount of dust is created, comprising the ground particles of the rail as well as the abrasive and binder particles torn from the grinding wheel.

Déjà lorsqu'on travaille en plein air ces poussières de meulage sont gênantes pour le personnel et elles le sont encore plus lorsque le travail s'effectue dans des tunnels ou galeries, comme cela est le cas sur la presque totalité du trajet dans les réseaux de métros par exemple.Already when working in the open air, this grinding dust is inconvenient for the staff and it is even more so when the work is carried out in tunnels or galleries, as is the case for almost the entire journey in the networks of metros for example.

La présente invention tend à remédier aux inconvénients précités et a pour objet un dispositif d'abattage des poussières de meulage d'un véhicule ferroviaire équipé d'unités de meulage des rails de la voie ferrée, comme décrit par exemple dans le CH-A-529 260, qui se distingue par le fait qu'il comporte des moyens formant, à proximité des unités de meulage, une nappe de brouillard captant les poussières et les abattant sur le sol.The present invention seeks to remedy the aforementioned drawbacks and relates to a device for removing grinding dust from a railway vehicle equipped with units for grinding the rails of the railway track, as described for example in CH-A- 529 260, which is distinguished by the fact that it comprises means forming, near the grinding units, a layer of mist capturing the dust and blowing it down on the ground.

Les figures 1 et 2 illustrent un véhicule ferroviaire meuleur muni d'une première forme d'exécution du dispositif d'abattage des poussières.Figures 1 and 2 illustrate a grinding rail vehicle provided with a first embodiment of the dust suppressing device.

Ce véhicule 1 comporte un châssis roulant auquel sont fixées de façon réglable des porte-outils 2 comprenant plusieurs unités de meulage 3 chacun. La fixation et le réglage de ces porte-outils ainsi que des unités de meulage s'effectue de façon conventionnelle, comme décrit par exemple dans le brevet CH-A-529 260.This vehicle 1 comprises a rolling chassis to which are fixed adjustable tool holders 2 comprising several grinding units 3 each. The fixing and adjustment of these tool holders and of the grinding units is carried out in a conventional manner, as described for example in patent CH-A-529,260.

Des vérins reliant les porte-outils 2 au véhicule I permettent d'appliquer des unités de meulage 3 contre le rail R avec la force désirée pendant le travail.Cylinders connecting the tool holders 2 to the vehicle I make it possible to apply grinding units 3 against the rail R with the desired force during work.

Le dispositif d'abattage des poussières de meulage comporte des moyens formant à proximité des unités de meulage, une nappe de brouillard captant les poussières et les abattant sur le sol.The grinding dust removal device comprises means forming, near the grinding units, a layer of mist capturing the dust and dropping it on the ground.

Ces moyens comportent un conduit 4, disposé sur le pourtour du véhicule 1 légèrement en-dessus des unités de meulage 3, présentant des orifices ou canaux d'éjection 5 répartis sur toute la longueur du conduit 4 et dirigés vers le bas. Ce conduit 4 est constitué par exemple par quatre sections rectilignes s'étendant chacune sur un côté du véhicule, reliées par des raccords d'angle, non illustrés, permettant une rotation sur elle-même de chaque section. Chaque section du conduit 4 est maintenue sur le châssis du véhicule 1 par des brides 6 permettant une orientation angulaire de cette section de manière à diriger les orifices 5 dans la meilleure direction pour créer une nappe de brouillard suffisamment proche des meules 7 pour permettre de capter les poussières de meulage de celles-ci.These means comprise a conduit 4, disposed on the periphery of the vehicle 1 slightly above the grinding units 3, having orifices or ejection channels 5 distributed over the entire length of the conduit 4 and directed downwards. This conduit 4 is constituted for example by four rectilinear sections each extending on one side of the vehicle, connected by corner connectors, not shown, allowing each section to rotate on itself. Each section of the duct 4 is held on the chassis of the vehicle 1 by flanges 6 allowing an angular orientation of this section so as to direct the orifices 5 in the best direction to create a sheet of fog sufficiently close to the grindstones 7 to allow picking up grinding dust from them.

Le dispositif d'abattage des poussières de meulage comporte encore des moyens de production d'un fluide et de distribution de celui-ci aux moyens formant ledit brouillard. Das cette première forme d'exécution ces moyens de production de fluide formant la nappe de brouillard comportent un échangeur de chaleur 8 dont le circuit primaire est alimenté par les gaz d'échappement d'un moteur thermique 9 servant à la propulsion du véhicule et à l'entraînement d'une génératrice 10 électrique fournissant le courant électrique aux unités de meulage et aux installations diverses du véhicule.The grinding dust removal device also includes means for producing a fluid and distributing it to the means forming said mist. In this first embodiment, these means of producing the fluid forming the fog layer comprise a heat exchanger 8, the primary circuit of which is supplied by the exhaust gases of a heat engine 9 used to propel the vehicle and to driving an electric generator 10 supplying electric current to the grinding units and to the various installations of the vehicle.

Les gaz d'échappement du moteur thermique 9 ayant traversé l'échangeur de chaleur 8 sont évacués dans l'atmosphère.The exhaust gases from the heat engine 9 having passed through the heat exchanger 8 are discharged into the atmosphere.

Le circuit secondaire de l'échangeur de chaleur 8 est formé par un serpentin 11 dans lequel une pompe 12 envoie de l'eau puisée dans un réservoir 13. Cette eau est vaporisée lors de son passage dans l'échangeur de chaleur 8 par les calories qui lui sont délivrées par les gaz d'échappement et la vapeur ainsi obtenue est distribuée par un ou plusieurs canalisations au conduit 4. Cette vapeur d'eau s'échappe sous pression par les orifices 5 et crée ainsi autour de la partie inférieure du véhicule une nappe de brouillard confinant les particules de poussières de meulage.The secondary circuit of the heat exchanger 8 is formed by a coil 11 in which a pump 12 sends water drawn from a reservoir 13. This water is vaporized during its passage through the heat exchanger 8 by the calories which are delivered to it by the exhaust gases and the steam thus obtained is distributed by one or more pipes to the duct 4. This water vapor escapes under pressure through the orifices 5 and thus creates around the lower part of the vehicle a layer of fog confining the particles of grinding dust.

En effet, la poussière de meulage est captée par cette nappe de brouillard et les poussières humidifiées tombent au sol. On empêche ainsi efficacement la projection des poussières de meulage dans l'atmosphère réalisant ainsi le but recherché.Indeed, the grinding dust is captured by this layer of fog and the humidified dust falls to the ground. This effectively prevents the projection of grinding dust into the atmosphere, thereby achieving the desired goal.

Les poussières de meulage sont de deux sortes, les poussières métalliques provenant du métal enlevé au rail et les poussières provenant de l'usure de la meule formée par un mélange de poussières d'abrasif et de liant.There are two types of grinding dust, metal dust coming from the metal removed from the rail and dust coming from the wear of the grinding wheel formed by a mixture of abrasive dust and binder.

Les poussières métalliques, relativement lourdes, sont projettées loin de la zone de meulage et vers le bas, elles se déposent sur la voie ou à proximité de celle-si sans causer de dommages ou grâves inconvénients.The relatively heavy metal dust is thrown away from the grinding area and downwards, they settle on or near the track without causing damage or inconvenience.

Il n'en va pas même des poussières provenant de l'usure de la meule qui sont extrêmement fines et légères. Grâce au rideau de vapeur entourant le véhicule, on empêche efficacement que ces poussières fines et légères s'échappent dans l'atmosphère. Quant aux poussières fines et légères projetées vers le centre de la voie, il est indiqué d'éviter leur accumulation dans le véhicule et l'on prévoit à cet effet (voir figure 2) une aspiration centrale des poussières créant une dépression sous le véhicule meuleur. Le courant d'air chargé de particules ainsi aspirées est filtré avant d'être restitué à l'atmosphère. Cette aspiration est réalisée au moyen d'une soufflerie 18, entraînée en rotation par un moteur 19, placé dans un conduit d'aspiration 20.The same does not apply to dust from the wear of the grinding wheel which is extremely fine and light. Thanks to the steam curtain while turning the vehicle, this fine and light dust is effectively prevented from escaping into the atmosphere. As for the fine and light dust projected towards the center of the track, it is advisable to avoid their accumulation in the vehicle and there is provided for this purpose (see Figure 2) a central suction of dust creating a vacuum under the grinding vehicle . The air stream charged with particles thus sucked in is filtered before being returned to the atmosphere. This suction is carried out by means of a blower 18, driven in rotation by a motor 19, placed in a suction duct 20.

Comme les véhicules meuleurs ont un encombrement imposé et faible pour loger toutes les installations nécessaires, il est souvent difficile de loger des réservoirs d'eau de grande capacité, c'est pourquoi il est important d'utiliser cette eau le plus parcimonieusement possible, c'est-à-dire de créer le plus de brouillard possible pour une quantité d'eau donnée. La vaporisation de l'eau représente à cet effet un grand avantage par rapport à une simple pulvérisation d'eau.As the grinder vehicles have a small and imposed footprint to accommodate all the necessary facilities, it is often difficult to accommodate large capacity water tanks, which is why it is important to use this water as sparingly as possible, c is to create as much fog as possible for a given amount of water. For this purpose, spraying water is a great advantage compared to simply spraying water.

Il est intéressant de noter que l'énergie nécessaire à la production de vapeur d'eau est obtenue par la récupération de calories des gaz d'échappement qui sont sans cela perdues.It is interesting to note that the energy necessary for the production of water vapor is obtained by recovering calories from the exhaust gases which are otherwise lost.

Des essais en galeries ont prouvé que ce procédé d'abattage de poussières était extrêmement efficace et qu'il était possible de supprimer les équipements spéciaux de ventilation de l'intérieur du véhicule.Gallery tests have shown that this dust suppression process is extremely efficient and that it is possible to remove special ventilation equipment from inside the vehicle.

Une autre conséquence de l'utilisation de ce dispositif d'abattage des poussières de meulage est l'absence de souillures ou de salissures des stations ou gares souterainnes notamment dans les réseaux de métropolitain.Another consequence of the use of this grinding dust removal device is the absence of soiling or soiling from underground stations or stations, especially in metropolitan networks.

Dans une variante du dispositif illustrée à la figure 3 le conduit 4 et ses orifices 4 sont remplacés par des conduits 14, 15 alimentant en vapeur d'eau des buses 16, 17 dont les orifices sont dirigés en direction d'une meule 7.In a variant of the device illustrated in FIG. 3, the conduit 4 and its orifices 4 are replaced by conduits 14, 15 supplying water vapor to the nozzles 16, 17 whose orifices are directed towards a grinding wheel 7.

Une paire de buses 16, 17 est associée à chaque unité de meulage 3 et projette ainsi un brouillard de vapeur autour de la meule 7 captant les poussières de meulage de celle-ci.A pair of nozzles 16, 17 is associated with each grinding unit 3 and thus projects a vapor mist around the grinding wheel 7 capturing the grinding dust from the latter.

Dans cette variante, toutes les poussières sont abattues à proximité immédiate du rail meulé et ne peuvent pas se déposer sur les organes mécaniques du véhicule. On peut donc ici éventuellement renoncer à une aspiration centrale des poussières telle que décrite précédemment. Par contre, cette exécution peut entraîner une utilisation d'une plus grande quantité d'eau du fait du grand nombre de gicleurs utilisés.In this variant, all the dust is cut down in the immediate vicinity of the ground rail and cannot be deposited on the mechanical components of the vehicle. One can therefore here possibly renounce a central dust extraction as described above. On the other hand, this execution can involve the use of a larger amount of water because of the large number of nozzles used.

Pour capter les poussières de meulage, il est important de réaliser une ou plusieurs nappes ou zones de brouillard ou de gouttelettes finement réparties. Ceci peut être obtenu comme décrit ci-dessus par la projection de vapeur d'eau mais également de beaucoup d'autres façons.To capture grinding dust, it is important to make one or more layers or areas of fog or finely distributed droplets. This can be achieved as described above by spraying water vapor but also in many other ways.

On peut par exemple prévoir, comme indiqué schématiquement à la figure 4, que les gaz d'échappement du moteur thermique 9 soient directement délivrés dans le conduit 4, ou les conduits 14, 15. Dans une telle exécution, on prévoit une pompe 21 alimentant en eau sous pression un gicleur 22 placé dans la tubulure d'échappement 23 du moteur 9. Ainsi, on pulvérise de l'eau dans les gaz d'échappement chaud et on forme ainsi un mélange de gaz d'échappement et de vapeur d'eau propre à former les nappes de brouillard captant les poussières de meulage.It is possible, for example, to provide, as shown diagrammatically in FIG. 4, for the exhaust gases from the heat engine 9 to be supplied directly into the duct 4, or the ducts 14, 15. In such an embodiment, a pump 21 is provided supplying in pressurized water a nozzle 22 placed in the exhaust pipe 23 of the engine 9. Thus, water is sprayed into the hot exhaust gases and thus a mixture of exhaust gases and steam is formed. clean water to form fog layers that collect grinding dust.

Ce mélange de gaz d'échappement et de vapeur d'eau permettant la création des nappes de brouillard peut également s'obtenir, comme illustré schématiquement à la figure 5, par barbotage des gaz d'échappement dans un réservoir d'eau 24.This mixture of exhaust gas and water vapor allowing the creation of the mist layers can also be obtained, as illustrated diagrammatically in FIG. 5, by bubbling the exhaust gases into a water tank 24.

Comme les meules du véhicule ferroviaire meuleur sont orientables pour rectifier la totalité de la surface du champignon d'un rail, le conduit 4, respectivement les buses 16, 17 sont également orientables pour permettre la création de la zone de brouillard là où les poussières de meulage sont présentes.As the grinding wheels of the grinding rail vehicle are orientable to rectify the entire surface of the head of a rail, the conduit 4, respectively the nozzles 16, 17 are also orientable to allow the creation of the fog zone where the dust from grinding are present.

Il est évident que lorsque l'on utilise un train meuleur présentant un ou plusieurs véhicules tracteurs et des wagons meuleurs tractés la production du fluide servant à former le brouillard est réalisée sur les véhicules tracteurs comprenant le moteur thermique et ce fluide est distribué vers toutes les unités de meulage du train, c'est-à-dire celles portées par le véhicule tracteur et celles portées par les wagons.It is obvious that when using a grinding train having one or more towing vehicles and towed grinder wagons the production of the fluid used to form the mist is carried out on the towing vehicles comprising the heat engine and this fluid is distributed to all the train grinding units, i.e. those carried by the towing vehicle and those carried by wagons.
